Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.
This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.
Researchers studied groups of people from the University of Wisconsin-Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.
The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.
“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing,” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitve and Brain Science.
When our minds run out of working memory, these off-topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.
“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read,” study researcher Daniel Levinson, said in a statement.
People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.
The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.
小題1:The word “juggle” in the second paragraph can be replaced by “________”.
A.handleB.searchC.understandD.distribute
小題2:What can be concluded from Jonathan Smallwood's words?
A.People who often have daydreams probably own a pretty capable working memory.
B.On the working memory test, people with wandering minds will get high score.
C.Absorbed in the mind wandering, your attention left no space for your goal.
D.Dealing with some easy jobs, people with higher working memory will daydream.
小題3:What is the best title of the passage?
A.Mind drifts are always positive.
B.Daydreaming is good for the mind.
C.Creative moments come with working memory.
D.The more daydreaming, the more effectively one works.

Perhaps every older generation since ancient times has complained about young people, and today is no different. Isn’t it obvious that kids these days are self-absorbed social network addicts?
However, this summer, my impression of today’s kids has been restored by the story of Rachel Beckwith. She could teach my generation a great deal about maturity (成熟) and unselfishness — even though she’s just 9 years old, or was when she died on July 23.
At age 5, Rachel had her long hair cut off and sent to Locks of Love, which uses hair donations to make artificial hair for children who have lost their own hair because of cancer or other diseases. After that, Rachel announced that she would grow her hair long again and donate it again. And that’s what she did.
Then when she was 8 years old, her church began raising money to build wells in Africa through an organization called “charity: water”. Rachel was astonished when she learned that other children had no clean water, so she skipped her ninth birthday party. Rachel set up a birthday page on the charity: water website with a target of $300. Instead of presents, she asked her friends to donate $9 each to charity: water. Finally Rachel raised only $220 — which had left her just a bit disappointed.
Then, on July 20, a serious traffic accident left Rachel critically injured. Church members and friends, seeking some way of showing support, began donating on Rachel’s birthday page — charitywater.org/Rachel — and donations reached her $300 goal, and kept rising.
When it was clear that Rachel would never regain consciousness, the family decided to remove the life-support machine. Her parents donated her hair for the final time to Locks of Love, and her organs to other children.
Word spread about Rachel’s last fund-raiser (募捐行動(dòng)). Contributions poured in, often they donated $9. The total donations soon topped $100,000, then $300,000.
This is a story not just of one girl, but of a young generation of outstanding problem-solvers working creatively.
小題1:Which of the following is TRUE of Rachel?
A.She died at the age of 8.B.She was a cancer patient.
C.She was a warm-hearted girl.D.She founded Locks of Love.
小題2:The underlined word “skipped” in Paragraph 4 probably means “      ”.
A.put off B.gave upC.expectedD.planned
小題3:According to the text, Rachel set up the birthday page to       .
A.make more new friends
B.call on people to donate hair
C.a(chǎn)sk her friends to send her gifts
D.raise money to help African children
小題4:How does the author feel about the young generation now?
A.WorriedB.Critical.C.Appreciative.D.Doubtful
小題5:What would be the best title for the text?
A.Rachel’s last fund-raiser
B.Rachel and her birthday page
C.Kids are addicted to social networks.
D.What’s wrong with the young generation?

科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解

About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn’t help overhearing parts of their conversation. At one point the woman asked: “So, how have you been?” And the boy—who could not have been more than seven or eight years old—replied, “Frankly, I’ve been feeling a little depressed lately.”
This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn’t find out we were “depressed”, that is, in low sprits, until we were in high school.
Undoubtedly a change in children has increased steadily in recent years. Children don’t seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to.
Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists. Why?
Human development is based not only on born biological states, but also on patterns of access to social knowledge. Movement from one social role to another usually involves learning the secrets of the new status. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders.
In the last 30 years, however, a secret-revelation(揭示)machine has been installed in 98 percent of American homes. It is called television. Television passes information to all viewers alike, whether they are children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures.
Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practiced. Children must read simple books before they can read complex materials.
小題1:According to the author, feeling depressed is________.
A.a(chǎn) sure sign of a mental problem in a child
B.a(chǎn) mental state present in all humans, including children
C.something that cannot be avoided in children’s mental development
D.something hardly to be expected in a young child
小題2:Traditionally, a child is supposed to learn about the adult world________.
A.through connection with society
B.gradually and under guidance
C.naturally without being taught
D.through watching television
小題3:According to the author, that today’s children seem adultlike results from ________.
A.the widespread influence of television
B.the poor arrangement of teaching content
C.the fast pace of human scientific development
D.the rising standard of living
小題4:What does the author think of communication through print for children?
A.It enables children to gain more social information.
B.It develops children’s interest in reading and writing.
C.It helps children to read and write well.
D.It can control what children are to learn.
小題5:What does the author think of the change in today’s children?
A.He feels their adultlike behavior is so funny
B.He thinks the change worthy of note.
C.He considers it a rapid development.
D.He seems to be upset about it.

科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解

Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes.
Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected—compared with only one of those who had been sitting at the table, and none who had spent three days and nights together.
"The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold."
When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean ‘get rid of’, I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms (癥狀)—we're getting at the root cause too. "
小題1:Dr. Jack M. Gwaltney conducted the experiment in order to__________.
A.find out the most common cause of colds
B.infect the student volunteer
C.find out the role physical contact plays in the common colds
D.find out the role virus-laden air plays in the infection of colds
小題2:The result of the experiment shows that ___ plays an important role in the infection of colds.
A.sneezing at the infected person
B.touching the infected person
C.sitting together with the infected person
D.talking with the infected person
小題3:Which of the following statements is TRUE according to the passage?
A.Dr. Gwaltney was sure that hand-to-hand touch is the cause of the common cold.
B.Only one of the people who had spent three days and nights together became infected.
C.Dr. Gwaltney conducted many an experiment as to the cause of colds.
D.Dr. Gwaltney tested altogether 43 volunteers to see how they could develop colds.
小題4:Mr. Common Cold is______.
A.a(chǎn) newly-found virus
B.a(chǎn) nickname (綽號(hào)) of respect to Dr. Gwaltney
C.a(chǎn) method to cure colds
D.a(chǎn) way by which the other scientists laughed at Dr. Gwaltney
小題5:When Dr. Gwaltney gives a reply in the end of the passage, he means that______.
A.they have found the fundamental cause of colds
B.they have managed to wipe out the cold viruses
C.they have meant to experiment more
D.they have made much progress in dealing with colds
